PyMOL is an open-source, user-sponsored, molecular visualization system created by Warren Lyford DeLano and commercialized by DeLano Scientific LLC, which is a private software company dedicated to creating useful tools that become universally accessible to scientific and educational communities. It is well suited to producing high quality 3D images of small molecules and biological macromolecules such as proteins.

PyMOL is one of few open source visualization tools available for use in structural biology. The Py portion of the software's name refers to the fact that it extends, and is extensible by, the Python programming language.

[edit] Non-free binaries

On August 1, 2006, DeLano Scientific adopted a controlled-access download system for precompiled PyMOL builds (including betas). From now on access to these convenient and ready-to-run executables will be limited to paying customers only. The source code will continue to be provided at no cost as well as older precompiled builds.
